## Long description

Purmo RS-KOSZ DO FILTRA 11/4 ARKO is a replacement filter housing cap designed for filtration systems with a 1¼" connection. It functions as a sealing and mounting component for filter cartridges, ensuring secure attachment and leak-free operation in heating and water treatment installations. The cap is intended for use where a robust, form-fitting closure is required to maintain system integrity and facilitate cartridge replacement.
Advantages
The housing cap provides a reliable seal and stable mechanical support for compatible filter cartridges, helping to prevent leaks and reduce the risk of system downtime. Its standard 1¼" connection format simplifies installation and makes it suitable for many common heating and water filtration arrangements. The part is produced to fit the corresponding filter body, enabling straightforward replacement and maintenance without the need for custom adapters.
Suitable for
 Replacement of worn or damaged filter housing caps in domestic and commercial heating systems
 Water treatment and filtration assemblies with a 1¼" inlet/outlet connection
 Routine maintenance where cartridge removal and resealing are required
Key specifications
 Connection size: 1¼" (standard threaded fitting for filter housings)
 Function: sealing and mounting component for filter cartridges
 Compatibility: designed for use with matching Purmo filter bodies and ARKO-series cartridges
 Application areas: heating systems, water treatment installations
How to use
Turn off the water or isolate the section of the system before attempting to replace the filter housing cap. Release system pressure and remove the old cap by unscrewing it from the filter body. Inspect the sealing surface and replace any worn gaskets, then fit the Purmo RS-KOSZ cap by threading it onto the filter housing until it seats evenly. Hand-tighten and, if required by the installation instructions, apply the recommended torque using a suitable tool. Restore pressure and check for leaks at the connection points before returning the system to normal operation.
Usage recommendations
Use only compatible gaskets and follow the manufacturer's guidance for tightening to avoid overtightening. Inspect seals periodically and replace the cap if cracks, deformation or persistent leaks occur. For safe maintenance, isolate the system, relieve pressure and wear appropriate protective equipment when servicing filter housings.
